Frequency resolution, temporal resolution and loudness function as the basic hearing characteristics were measured for some hearing-impaired listeners (IMs) with mild to moderate hearing loss as well as for normal listeners (NMs) . All IMs suffer deterioration in their hearing characteristics.Articulation score and confusion of consonants in VCV syllables were collected for some silent intervals between a preceding vowel and following consonants. Articulation scores of stop consonants of/d/and/t/obtained by a IM showed low value at the short silent interval, while the scores progressively improved as the silent interval increased. Gap detection threshold as a temporal resolution for this IM was about twice higher than that for NMs. It is suggested that his lower performance in consonant identification may come from lower temporal resolution, that is, the effective duration of forward masking of preceding vowel toward consonant is longer for the IM than for NMs.Next, another IM particip … More ated in articulation test of VCV syllables at some sound levels. His loudness function was simulated to NMs, then articulation scores obtained by the IM and those by NMs through simulated hearing impairment were compared. The results of simulated hearing-impairment showed that the deterioration in articulation scores as lowering sound level for the IM reappeared in the simulation paradigm.Further, adding his temporal resolution (temporal transfer function) and frequency resolution (auditory filter characteristics) to the characteristics to be simulated, articulation tests for NMs were done under the simulated conditions with various combination among IM's three hearing characteristics. Comparison between IM and NMs (simulated hearing impairment) was made as for articulation score of consonants and for information transfer rate of consonantal distinctive features. The speech reception ability of IM reappeared best in the performance obtained by NMs (simulated hearing impairment) when three all hearing characteristics of IM were combined. It is supposed that temporal resolution of this IM may not affect his speech reception. Less

以频率分辨力、时间分辨力和响度函数为基本听觉特征，对部分轻度至中度听力损失的听障者和正常人进行了测试。所有的IM遭受恶化，他们的听力特征。清晰度得分和混淆的辅音VCV音节之间的一些无声的间隔前元音和以下辅音收集。通过IM获得的/d/和/t/的塞音的清晰度分数在短的无声间隔中显示出较低的值，而分数随着无声间隔的增加而逐渐提高。间隙检测阈值的时间分辨率为这个IM是约两倍高于NM。研究结果表明，他在辅音识别中的低表现可能来自于较低的时间分辨率，即前元音对辅音的前掩蔽作用的有效持续时间IM比NM长。 ...更多信息 在VCV音节清晰度测试中，将其响度功能模拟到神经肌肉上，然后将IM和神经肌肉模拟听力损伤所获得的清晰度评分进行比较。模拟听力损伤的结果表明，在模拟范例中再现了IM的清晰度评分随声级降低而下降的情况，进一步，将IM的时间分辨率（时间传递函数）和频率分辨率（听觉滤波特性）添加到待模拟的特性中，在IM的三个听力特性的不同组合的模拟条件下对NM进行清晰度测试。比较了IM和NM（模拟听力障碍）的辅音清晰度得分和辅音区别性特征的信息传递率。当IM的所有三个听觉特性相结合时，IM的言语接收能力在NM（模拟听力障碍）获得的性能中再现最好。据推测，这个IM的时间分辨率可能不会影响他的言语接收。少
